Abstract
PURPOSE: To read a character pattern vertically and horizontally at a high speed by a character pattern generator, which is able to read patterns vertically and horizontally, by improving the read speed by eliminating the conversion of data by a buffer memory.
CONSTITUTION: This device is equipped with character pattern memory circuit 11 which decomposes several character patterns into dot matrixes of a P number of bits making it possible to read them in either vertical or horizontal direction under the control of computer 12 and is stored with those decomposed character patterns on a P2-bit unit, and address converter circuit 21 which generates a conversion address by converting the address signal from the vertical direction to the horizontal direction or in reverse. Then, selector circuit 22 is provided which selects the conversion signal from circuit 21 and by a read-direction assignment signal and sends the selected signal to circuit 11, and further, multiplexer 23 is also provided which receives P2-bit unit signals from circuit 11 at one input terminal in the sequence of vertical direction and at the other input terminal in the sequence of horizontal reading to generate character patterns by selecting the read-out direction by a read- direction assignment signal.
